ASCA observation of a near-by cluster, Antlia Original Research Article

Results from ASCA observation of the Antlia cluster are presented. The Antlia cluster is a poor cluster very near to our galaxy which has a redshift of 0.0087. There was no X-ray central excess brightness frequently seen in near-by poor clusters, such as Fornax and Centaurus, so the gravitational potential seems to have only a single component. This is the second near-by poor cluster of such type next to A1060 and it became clear that there is a variety in the potential structure between the clusters.
